VAPOR-BURNER STOVE.

SPECIFICATION forming part of Letters Patent No. 325,592, dated September 1, 1885.

Application filed December 13, 1894. (No model.)

To all whom it may concern.-

Be it known that I, ZEBULON DAVIS, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burner Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in vapor-burners; and it consists, first, in the combination of the generating-burner, a support therefor, a pipe for conducting the vapor, the conducting-pipes, having their inner ends turned at an angle to their length, and needlevalveslocated outside of and beyond the ends of the pipes; second, the combination of the generating-burner, a support therefor, a pipe for conducting the vapor, the conductingpipes, having their inner ends turned at an angle to their length, needle-valves for controlling the flow of vapor, and a suitable means at the inner ends of the pipes for the purpose of preventing the flame from one burner from interfering with the flame of the other burner; third, a vapor-burner provided with two horizontal rows of apertures and havingatube formed therewith and in between the two rows of apertures, the tube being formed partly within and partly without the burner, all of which will be more fully described hereinafter.

inverted view of a portion of the burner. Fig.7 is a perspective of the burners and their attachments.

A represents a stand-pipe, and B the generating pipe or tube which extends therefrom, and which is cast in a single piece with the burner b, as shown in Fig. 2.

This tube or chamber extends horizontally around the burner, and is located midway between the two rows of apertures in the burner, so that the flames from both rows of apertures will play upon this tube or chamber and heat it to a very intense degree, even when the flames are turned down low. This tube, being located as here shown, and being heated to such an intense degree, generates vapor rapidly and in sufficient quantities not only to supply this central generating-burner, but the blllllGIS which are placed upon the conducting-pipes at a suitable distance beyond it.

Heretofore a generating tube or chamber Y has been formed around the extreme upper portion of a wire gauze burner; but in this case the tube or burner is placed in such a position that it is only affected by the heat of a single row of apertures. By locating this tube in between two rows of apcitures, as here shown, it is heated both above and below, and a greater amount of vapor is generated. When this central burner is not in use, in order not to waste fuel, the flame should be turned down as low as possible, and then this central burner serves as a generator for the burners placed upon the conducting pipes. As the gas must be generated rapidly to supply both burners, it is necessary that this tube or chamber should be thoroughly heated, even when the [lame of the central burner is turned down. \Vherc the tube or chamber is located at the top of the burner and only affected directly by a single row of apertures, a sufficient quantity of gas cannot be generated to supply other burners when the flame is turned down.

The vapor-tube B has a needle-valve, D, passed through it at right angles, as shown in Fig. 1, for the purpose of supplying vapor to this central burner. The lower end of the vapor-tube, as shown in Fig. 6, has its end turned in opposite directions, and the escape of the vapor from each end regulated by a needle-valve, F. These needlevalves F preferably extend horizontally outward, and are placed entirely outside of andbeyond the two ends of the conducting-pipes G, in contradistinction to being located between the pipes. These two valves F are provid ed,respectivcly, with right and left threads, and the outer end of each screw is provided with a handle, H, as shown in Fig. 3. The needle valves, having threads which are cut in opposite directions,

are moved in opposite directions for the pur-' pose of turning on and shutting off the vapor.

These valves, being located beyond the ends of the conducting-pipes, as here shown, enable' needle-valves to be used, which cannot be donc where the valves are located between the ends of the pipes, as has heretofore been done.. Where needle-valves are used the points of the needles always keep the apertures open; but where plug-valves are used, as must be done where the valves are located between the ends of the pi pes,the vaporapertures soon become clogged from the heavy carbonaceous matter in the oil or fluid, and then the stove is rendered utterly inoperative until this matter has been cleaned out. As this cannot be readily done by inexperienced persons, and especially when the stove is hot, the stove becomes practically disabled, and thus much trouble and annoyance is caused.

The conducting-pipes G have their inner ends turned at an angle to the length of the pipe, and secured together, as shown, just beopenings 1 are not used for this purp0se,apartition, J, may be extended from the ends of the pipes in between the two burners, as shown in Fig. 4, and thus effect the same object. Where no means are taken to prevent the flame from one burner communicating with that of the other, when one burner is shut off a slight explosion follows,which will sometimes not only put out the flame oftheburner upon the other conducting-pipe, but also put out the flame of the generating-burner at the same time. If this extinguishment of the other burners is noticed, they can be readily lighted again, but if it is not noticed the escape of the vapor and fluid takes place through them, to the great danger not only of the operator, butto the building in which the stove is being used.

Upon each conducting tube or pipe G are placed one or more burners, O, which are preferably made of light perforated sheet metal, as shown in Fig. 5. If the flames burn directly from the apertures through "this sheet metal, the heat soon destroys it. In order to prevent this I take a cylinder, (4, formed of a coiled wire, or a jacket made of thicker and heavier metal, and place it around the thin perforated metal, so that the flame will burn from the wire or perforated jacket rather than from the thin perforated metal. The jacket or cylinder serves to keep the flame from direct contact with the perforated metal, while the thin perforated metal serves to keep the flame from passing back into the conductingpipe. By means of a protector formed in this manner the thin perforated metal can be made to last much longer than where no jacket or protection is used. Inside of the burner, upon its bottom, is placed a thin perforated piece of metal'or wire-gauze, P, which serves to prevent the flame from following back through the pipe when the vapor is shut off. The burner becomes so intensely heated that the vapor catches fire from the inner side of the burner, and then the flame follows back through the pipe to the needle-valves, as already described. This guard, which is placed inside of the burner, serves to prevent theflame from passing back into the pipe.

Having thus described my invention, I claim--- 1. A vapor-burner, b, provided with two horizontal rows of apertures, and having a tube, B, formed therewith, and in betweenthe two rows-of apertures, the tube being formed partly within and partly without the burner, substantially as shown.

2. The combination of a generatingburne'r, a suitable support therefor, apipe, B, for con ducting the vapor,with the conducting-pipes, having their inner ends turned at an angle to the length of the pipe, and the needle-valves located at the ends of the pipes, substantially as set forth.

3. The combination of a generating-burner, a suitable support therefor, a pipe, B, for conducting the vapor, with the conducting-pipes, having their inner ends turned at an angle, the needle-valves located outside of and beyond the ends of the pipes, and a suitable means at the inner ends of the pipes for the purpose of preventing the flame from one burner from interfering with the other burners, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
